I have a Solarmax 40 filter that is several years old that I have been using with my Televue 85 refractor.

I have noticed recently that I have to set the T-max tuner all the way open to be able to see any prominences and features on the Sun's disk. It appears that the wavelength has shifted on my filter.

I also noticed that the lenses in the etalon sound like they are loose (they rattle if lightly shaken).

What do I need to do to "re-tune" my filter?
